Why use Sarkari Portal Online for Signatures?
Uploading a signature is tricky because the file size limit is very small (often 10KB-20KB). Normal compressors make the signature blurry and unreadable.
PhotoKB uses a special “High Contrast” method. We force the background to pure white and darken the text. This allows us to reduce the file size to 10KB while keeping the ink sharp and legible, meeting strict government requirements.
